UNITED STATES PATENT OFFICE BUILDING BLOCK John Joseph Olsen, San Francisco, Calif. Application September 22, 1933, Serial No. 690,548 3 Claims. (01. 72-30) The present invention relates to building blocks like, may be poured, as illustrated in Figure 1. and wall construction and moreparticularly to Blocks constructed in accordance with this inimproved blocks of light weight which canbe vention may be made of concrete, using stone or laid up in opposed relation to form the inside cinders, or any other suitable air or kiln drying and outside of a wall in a new and novel manplastic material. It is contemplated that the outner. i er surfaces of the slab portions of the blocks 10,

These will hold any aggregate poured therein in fixed blocks are individually illustrated in Fig re 2, vertical relation with the wall. For an illustration 3 and 4 of the drawing and are designated by th of this feature reference should be had to Figure numerals 10, 11 and'12. Each of the blocks 10 5 of the drawing, wherein the staggered relation comprises a slab forming portion 13 having proof the foot-portions 24, one above the other, is

jections 14 formed upon one side thereof so that c y w 1 I when the slab portions 13 are arranged in opposed It will be understood that the shape and disand staggered relation the projections 14 upon the position of the projections 18 and 20 and the opposed slabs will interlock with each other and projections 19, 21 and 23, upon the blocks 11 and provide vertical cavities between the slabs into 12 respectively, may be changed and that changes which an aggregrate 15, such as concrete or the may also be made in the number and shape of projections upon the side wall forming blocks without departing from the spirit of the invention. A modification in this respect is shown in Figure 6 of the drawing, wherein a block 25 is illustrated as having a slab forming p rtion 26 with a single projection 14.

In Figure 7 there is illustrated a block 27 having a slab forming portion 28 with two projections 29 of rectangular cross section. A modification of this latter form of block may also beobtained by forming the projections 19 with a dove-tail cross section.

In Figures 8 and 9 of the drawing thereis illustrated a further'modification' of an improved side wall forming block having projections which in-- terlock in the lateral ,and transverse directions soas to prevent both a separation of and a lateral movement between the opposed blocks. In this embodiment the block designated by the numeral 30 comprises a slab forming portion 31 having an,

outwardly extending hook like projection 32 with an upset base portion 33 that will engage the outside of an interlocking hook like portion 32 and prevent lateraldisplacement thereof. When the hook like projections 32 of opposed'slabs 31 are assembled in opposedrelat'ion, as shown in Figure '9 of the drawing, they will form a vertical cavity into which'cement or other aggre'gate 15 maybe poured to hold the blocks securely together, as is the case with the con-.

struction illustrated in Figure 1.

versed top for bottom, only grooves can be pro vided upon these blocks, unless right and left hand molds are used in forming "the blocks.

However, in the case of the side blocks a single mold can be used in formingall of these blocks.

When building a wall with these blocks the binding aggregate 15 can be'poured into the ver- 7 ticalcavities as'the wall' is built up or it can be' poured as afinal operation after the wall has been completed to the: desiredheightr If I addi-' tional strengthshould be required," reinforcing irons 35 may be located in these cavities before the aggregate is poured therein. ,The provision of suchreinforcing irons will not interfere with a pouring of the aggregate after the wall has been constructed. The improved blocks will also permit apouringof the aggregate during the construction of the wall as the blocks can be laid' around the upwardly projecting irons without being threade'dtherover as would'be the case were the cavities formed through asingle block. Afurther feature of advantage in a wall: 'constructed in accordance with the present invention is that there will be provided. vertical passageways betweenthe opposed'slab portions 13 and 14 through which the plumbing and electricwiring conduits may pass.

adjacent projections These passageways will also permit the disposition of a flue therein if desired. In this latter event it is contemplated that the fiue will'be particular shape of these units of each course against formed with a standard fired-clay lining 35, as illustrated in Figures 1 and 5 of the drawing. 7

While I have, for the sake of clearness and in order to disclose my invention so that the same can be readily understood, described and illustrated specific devices and arrangements, I desire to have it understood that this invention is not limited to the specific means disclosedgbut may be embodied in other ways that will suggest themselves, in view of this broad disclosure, to persons skilled in the art. It is believed that this invention is broadly new and .it is desired to,

claim it so that all such changes as come within the scope of the appended claims are to be considered as part of this invention. 7

Havingthus describedmy invention, what I claim and desire to secure by Letters Patent is 1. A building block comprising a surface form-f ing slab having two spacing projections formed upon the back surface thereof, said spacing projections being adapted to cooperate with like projections, upon similar slabs and form a vertical cavity between the slabs into which an aggregate may be oppositely extending foot portion upon each of said projections adapted to extend into said cavity and interlock horizontally and vertically with said aggregate, to secure the slabs together in opposed staggered andsuperimposedstaggered and outside surfaces 7 relation to form the inside of a wall. V. l

2., A wall construction "comprising .a plurality of surface forming slabs laid layer upon layer in staggered relation to form' one surface of a wall, other surface forming slabs laid layer upon layer in staggered relation with each other and poured when a number of said slabs'are laid up in two parallel courses, and an.

in spaced and staggered relation withsaid first 1 surface, iforming slabs toform another surface of the wall, each of said slabs being similar in construction and having spacing projections which form a continuous vertical cavity into which a binding aggregate may be. poured. and a laterally extending foot upon the end of each of said spacing projections adapted to pro,-

ject alternately in opposite directions and interlock with said aggregate to secure the slabs'together against displacement in and a vertical direction. 7

'3. 'In a wall construction, the combination of a 'course. of rectangular units disposed layer upon layer to formone surface of a wall, a second course of similar rectangular units disposed layer upon layer in opposed'parallel relationwith said first course of rectangular units and forming the other surface of the wall, the rectangularunits ofeach course being disposed in staggered rela:

tion with respect to each other in both a vertical and a horizontal plane,'and spacing projections upon said rectangular units having a laterally extending foot at the ends thereof, the location of the spacing projections upon said rectangularvertically extending units .being such that two aggregate containing cavities will' be formed within the length of each of said rectangular units and the disposition upon the'en'd of each of said spacing projections being'such that they will extend alternately into an adjacent cavity and interlock with theaggregate in said 'cavity' and hold displacement.
